I’d like more information on what is often called

I’d like more information on what is often called “Healing Powers of Crystals”.I would like to point out that I’m extremely sceptical towards this yoga and metaphysical belief, bt from a scientific point of view I have to admit certain crystals are capable of storing and/or emitting energy at various wavelengths.

I’d like to know more about these alledged powers to have a look at them from a strictly, sub-atomical scientific point of view.

Any help is welcome.

Thank you.
